Biography
Enzo was the illegitimate son of King Frederick II of Germany and Adelaide of Urslingen, the favorite and eldest illegitimate son of Frederick. With a pleasant personality and a strong resemblance to his father, he was married to Adelasia of Torres, the widow of Ubaldo of Gallura. This gave him half of the island of Sardinia, and in July 1239 he became imperial vicar of Lombardy and General-Legate in Romagna, taking part in his father's campaigns in Italy. In 1247, he took part in the failed siege of Parma, but he was captured on 26 May 1249 at the Battle of Fossalta by the Lombard League. He died in prison in 1272, and he was the last member of the House of Hohenstaufen; Conradin had died four years earlier.
